    Moon

    From the album: The Moon

  2. I'm currently on my annual leave in Italy and the sky has been clear all day with no air turbulence. The telescope is out - of course - and I managed a session before dinner. I thought about sharing some photos taken with my phone and a couple of sketches.
  3. 9 August was a good night for the Moon, so I studied the region from Ptolemaeus to Arzachel at 231x. Especially Alpertragius stood out, with its oversized central mound. It has been suggested that this is a volcanic feature. Herschel too was quite prominent. Thanks for watching.
  4. Recently I was given a 4 inch skywatcher Newt for which I made a table mount. I thought I would see what you could do imagining wise using this scope and a mono ASI220. 200 frames at full resolution, stacked in Autostakert, processed in Registax6 and given a final polish in Windows Photo. Conditions far from ideal with thin high cloud. I guess the previous owner will ask for it back...…..
  5. Yesterday the Moon was low in the sky (in Scorpius), but he seeing was good and allowed magnifications up to 257x. Gassendi was the most prominent crater on the terminator. Here's a painting of the scene. The small Moon image (Stellarium) shows the location of Gassendi. Thank you for watching.

    Moon - Maurolycus

    Good seeing yesterday night. I spent some time on the Moon after it cleared the trees. Maurolycus captured my attention. Here's a painting of the scene:
  7. c925 and 294mc pro bin 1 with ir/uv cut filter. 2 panel mosaic best 25% of 1,000 . Had to convert to jpeg as i keep getting an error 200 when trying to upload a larger file. ( 50+ mb ) clicky for full rez. and a few with the 385c camera with neodymium filter and mostly barlowed.
  8. Second time I undertake this kind of endeavour. Many many movies were shot. Over 300Gb of data. Stitching was done by hand. in adobe Photoshop. Equipment used: CFF 300f//20 cassegrain ASI174MM with Astronomik proplanet807 processing using Autostakkert, lynkeos and adobe photoshop. Image is a wee bit too large to add to post direclty. hence just the link. https://astrob.in/400728/0/ Make sure to check out at full res. enjoy. Wouter.
  9. I took this one and forgot about it for a while. Ended up pretty happy with the end result. D300 attached to the back of my LX200 OTA ACF Meade. It is quite hard to get the clarity though from a single frame.
  10. An apology to all my DSO hunting friends. I have sold out. After just a handful of hours with the fuzzies over the past four months, I spent a slightly hazy Moon-filled night with some of the more local objects. 13 - Egeria was a reasonably easy star hop from Iota and Kappa Ursae Majoris and despite the less than helpful conditions was not too troublesome in identifying at magnitude 10.3. I spent a few moments with Jupiter. Two moons were on each side of the planet and were fairly evenly spaced. No sight of the GRS but three bands were easily visible. I left the 5mm X-Cel eyepiece (127x) with a 25% neutral density filter in and moved on to the Moon and spent some time identifying some of the landmarks close (or thereabouts) to the terminator. I started at Mare Ibrium, punctuated to the South by a perfect view of Copernicus. Moving slightly away from the terminator and North was Eratosthenes and the Apennine mountains but a much feinter halo Stadius was also possible to make out. I also identified Archimedes, Eudoxus, Aristoteles and Plato before finishing with Mare Frigoris in the North. The next leg of identification started from Mare Nubium, Ptolemaeus and moved South to Tycho and Maginus. I concluded the night with Mare Serenitatis, Tranquilitatis and Vaporum and some of the more obvious signpost craters. Menelaus was nice and lead to a reverse "horn of Africa" which pointed to Plinius (named after the Younger or Elder?). Bessel was quite easy to see against the smooth backdrop of the Sea of Serenity as was Manilius, farther South and closer to the terminator. I appreciate that many of these aren't particularly challenging but I have never bothered logging / reporting them before and I have to start somewhere. I will have to add the lunar 100 to my signature, I guess. ____________________________________________________________ Observing Session: Tuesday, 19th February 2013, 19:00 hrs to 20:35 hrs GMT VLM at Zenith: 4.5 ish New - Revisited - Failed
  11. The full moon rising over Tiran Island in Sharm el Sheik, Eygpt. Canon 5D MkII and Canon 100mm macro lens. Sometimes the rules of composition should just be ignored
  12. Hi all, Not posting much in SGL of late but I am still imaging as much as I ever did. Here's a 166-pane hand stitched mosaic from August 10th when the Moon was at last quarter phase. The separate panes were caught between 04:06 and 04:49 BST using a C-14 at prime focus and a PGR Flea-3 camera. The image is too large to show in one hit so I'm presenting it in a zoomable format - just follow the link... http://www.zoom.it/ephS#full Best regards, Pete
  13. As there haven’t been too many clear nights lately, when I saw the cloudless sky yesterday I decided to get a scope out and spend some time observing. With the moon near full it seemed the obvious target. I also wanted to make a start on some sketching which I’d promised myself I would try again this year. I’m glad I did, conditions were great, there was no wind, no dew and the seeing was really good and I was amazed how steady the image was as I upped the magnification to around 300x in the end. I settled into a camping chair for comfort and slowly moved up and down the terminator enjoying the wealth of detail. From the ragged shadows cast by the walls of Pythagorus and Carpenter and then down towards a feature which I think would be Briggs, the rim of which seemed to float miles above the lunar surface with its base still in shadow. The area I settled on to sketch was around Aristarchus, Herodotus and Vallis Shroteri. If I’m honest that’s mainly because that area seemed a little less overwhelming to try and draw. I’d forgotten how relaxing the whole thing was, and I think it’s true you do really see that little bit more if you sketch, as every time I returned to the eyepiece another smaller crater or subtle feature would appear, like the craterlet Herodotus N which is only a couple of miles across. I spent around 45 minutes sketching and around an hour and half just enjoying the views. The end result wasn't up to much but I really enjoyed my time and if I keep at it who knows I might just overcome my lack of artistic talent. Dan

  15. I spent a fair amount of Wednesday afternoon centering my polar scope... Little did I realise that the polar scope requires centering before you even attempt perfect polar alignment. It appears that my AVX has been very forgiving in the fact that in the past I have more or less just got polaris somewhere near the centre of the circle before aligning. However, after watching many YouTube clips on how to centre the polar scope I finally achieved my aim in having the polar scope centered. Last night was my first serious attempt at 'Bang on' polar alignment with a well centered polar scope!! For some time I've been moaning about having to scramble around on the floor bending my knees and neck looking up for polaris through the polar scope! last night I raised my tripod to almost full extension and managed to look through the polar scope sat comfortably on a picnic chair. I started setting up early so used my compass during the early evening to point north ready for the appearance of polaris... Wow! when Polaris appeared I wasn't far out :-) I rotated the the reticule so the view through the polar scope matched what I could see in the sky with the plough above the centre circle, a quick tweak and 'Bingo' Polaris was spot on where it should be... let the fun begin!! Oops before I did that I freelanced over to the crescent moon situated between two rooftops from my observing location... stunning! I tend to always overlook how wonderful the surface of the moon looks at high mag... Whilst observing using my Starwave 102 and a Vixen NPL 20mm I could see what looked like two bright spots at the top of the crescent like tiny stars. On closer observation I figure these must of been a couple of mountain tops caught in the sunlight... That was amazing, would lover to know the name of those peaks! Here is my list of targets bagged using a combination of a Celestron 32mm, Vixen NPL 20mm, Meade 12 & 18mm, a trusty BST 8mm and for Jupiter a blue filter. Jupiter, M5, Epsilon Lyrae 1,2, Zeta Lyrae, Xi Bo, Theta 2 Can, Tegman, Kappa Bo (Loved this) Iota Cancer, Graffias, Delta Serpens, Theta Serpens, Algieba (Leo) Coma Star Cluster Melotte 111 Toward the end of the session I practised entering the RA & Dec into the handset, hitting targets pretty much bang on (very pleasing)... Although when referencing the 'Double Stars for small telescopes' book by Sissy Haas the coordinates given are not as long in numbers as the ones on the handset... I still hit the targets bang on though so was delighted. Nicks Tips No 5 - Throwing a blanket over the washing line to create a dark space removing a cluster of 3 streetlights 100m away over the neighbours fence... Genius!
  16. Here are images of the moon I did with my new scope, happy so far, and i know those are not good enough processed, but with that simple i can be proud that i can have good results, these are for now my best moon shots so far, and still i have some not processed, i don't know if seeing was great excellent or fair or poor, i just care I've got results.
  17. Hi, although Ive been doing lots of deep sky imaging Ive not really done any serious lunar imaging at all. Here is my first try with ASI1600MM-C and 12" f/10 Meade SCT on EQ8. I took 4 panels with 850nm IR pass filter, 20 frames stacked in each panel out of 500. Image is quite large, at 1:2 scale out of the original. There is plenty of intresting details around Mare Crisium. Unfortunately seeing wasnt stable enough the top panel would be as sharp as the rest is. Still Im quite happy with the results. C&C welcome.
  18. Just messing with some more data I got from imaging the moon on Thursday 22nd February, and in the attached image below I’ve cropped in closer to the area around the Lunar V feauture, which shows quite a lot of detail with my early attempts with my ZWO ASI 120 MC camera, attached to my Celestron Omni 120mm f8.3 ‘frac. Processed through Registax, touched up in PS, and then on iPad Pro photo app Aviary also.
  19. Taken with smartphone Samsung Galaxy fame(GT-S6812) no lens, barlow 2x, 150mm chinese mirror kit, dobsonian mount homemade....Unfortunately processed on computer(no bonus consideration, i know rsrs). Stacking with AS!2, processed with Registax 6 and photoshop.
  20. Thought I should at least enter this, although I generally stay away from competitions where I am not the only judge . This is a shot of Plato plus surroundings, taken with an iPhone 6 Plus handheld at the eyepiece. Scope: Tak FC100DC (another 50p in the swear box!) Eyepiece: 3 to 6 Nag Zoom at 3mm setting (I think!) giving x246. Mount: AZGTi on Gitzo tripod Taken using Procam 4 and cropped and processed using PS Express, all on the phone.
  21. I took this image on the 4th Nov over the space of about half an hour from 2215UT. This mosaic is made from 18 frames, each of them is 3000 frames, with the best 12% stacked within Autostakkert2. Total data size was 52.6GB - all using an ASI120MM through a 350mm newt at f4.52 with a 742nm nr-IR filter. Each of the frames was processed identically in Registax6 with Wavelets, etc. and then saved as a fits file. At this point, I took the images into ICE and combined them into one large mosaic, and then post processed in PS (levels, slight smart sharpening, curves and background levels). I did also try using photomerge in PS CS4, but interestingly, ICE did a better job (marginal, but there were a couple of edge artifacts with photomerge). Beware for those on slow connections: the full size file is quite big at 7.3MB, even as a jpg...thanks for looking!
  22. From 30th October 2017. Using a Sky & Moonglow filter that was included with the collection, I didn't know what to expect out of it. (I had previously used a moon filter that left a green tint to everything - the detail was there, but the colour was flat.) This filter didn't cut out as much of the colour, despite having a mild pink hue. I'm still familiarising myself with everything, but I'm looking into things as I go. This image is a combination of 7 exposures at various speeds to allow for detail and contrast using a Canon Rebel T5i (gifted to me, so I'm not complaining about a free DSLR) and my Celestron Nexstar 127SLT. I aligned the images in Photoshop CC, and adjusted using Lightroom and the Camera Raw filter to help pull out the colours. I'm excited to keep experimenting with things, and happy to submit this image for review.

  24. Effectively my first light on this sight. Need to concentrate on the focusing but your comments would be much appreciated Moon framed.bmp
  25. I made a gif from my moonrise video, what was taken with Huawei P10 smartphone and Celestron Nexstar 8 SE telescope. 25mm plössl eyepiece used.
